In the CreateUserWizard control, I have added a new textbox in the CreateUser step. I'd like to run a check on the data entered, and depending on what it is, prevent the user from being created. I figure I would use the CreatingUser event, but I'm not sure how to prevent the user from being created after that. Can I do it there, or will I have to let the user get created and then delete the user at the end of the wizard? ...
